Correct answer: E — Granulomatosis with polyangiitis
Granulomatosis with polyangiitis is the single best answer because ENT disease, cavitating lung nodules and glomerulonephritis with PR3-ANCA indicate GPA. The stem is testing diagnostic synthesis, not isolated recall, so the relevant clinical pattern and risk context determine the answer. Migraine is less suitable because it fits a different clinical pattern or a different treatment threshold; Sarcoidosis, Aspirin monotherapy and Etanercept do not address the key discriminator in this vignette. Clinical pearl: in SCE-style rheumatology questions, autoantibodies, imaging and synovial fluid findings should be interpreted with the whole phenotype.
